T0 @ZZ whom tm-ay concern:

Be it known that I, ROBERT W. VIEDER- WAX, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Burners, of which'the following is a specification.

This invention relates to burners, and more particularly to-oil burners. l

An object of the invention vis the provision of an oil burner having` separate retorts to preheat theoil and fluid employed to support combustion. n

A further object is the provision of a preheater for heating the fluid employed to support combustion which preheater will mate-` rially expand air or produce live steam when a mixture of oilvand steam is employed in the burner.

A further object yis the provision of a burner in which oil vapor is delivered to the burner pipe at an angle to the How of steam or vapor and is deflected -by the walls of the pipe to thoroughly mix the air of steamwith In ,the accompanying drawings, T have shown one embodiment of the invention. In this showing: v

vFigure 1 is a central vertical longitudinal sectional view, y f

Figure 2 is a transverse vertical sectional view on line 2-2of Figure l, and,

Figure 3 is a detail sectional view on line 3-3 of Figure 2;

Referring to the drawings, the reference numeral 1 designates a shell or tubular cas ing forming the bod)7 portion of the burner. This shell is provided with an open rearfend 2 and is further provided with 'inclined walls 3 adjacent the front end forming a restrict-y ed outlet 4. A tubular member 5 is arranged around the rear portion of the casing slightly spaced therefrom, forming an oil retort 6. One end of this tubular member is extended at an angle, as indicated at 7, and welded to the main casing, as at 8. The other end is provided with a flange 9. A similar tubular member 10 surrounds the forward portion of the casing and is spaced therefrom to form a preheater 11. This member is provided with a ange 12 at its rear end, spaced from the flange 9, and the adjacent ends of these members are adapted to be welded to the casing by-a filling 13 of metal. The forward end ofthe main casing is provided withy an offset portion'lc, adapted to receive a flange 15 on the forward end of the tubular member 10 and this flange is welded to the casing, as indicated at16. An oil delivery pipe 17 is .connected tothe retort 6, preferably at the vbottom andthe retort is provided with `a discharge pipe 18. An inlet pipey 26 is connected tothe preheater` and the -preheater is further provided with an outlet pipe 27. The pipe`27 lcommunicates with a valve casing 19, having a valve therein controlled'b7 valve stemv20.

vReferring to Figure 3 of the drawings, a burner pipe 21 is connected to the valve cas; ing by meansof a pipe22 and a union 23. A jet 241- is arranged within the pipe 22 and projects into vthe burner pipe. This jet is welded in the rear end of the pipe 22,v forming a'plug 25, of metal which prevents the the valve,.casing 19.

The pipe 18 is connected to a valve casing 28. The burner pipe 21 is provided with a branch 29, extending downwardly at an angle., This extension is connected to the passage of air, gas, or vapor'rearwardly into valve casing 28 by a pipe 30 anda union 31.-

pipe isv pro- OF ATLANTIC CITY, NEW JERSEY, CORPORATION 0F i When the burner 'is' employed with air, partially com-' pressed air is delivered to the preheater 11 i through the pipe 26. I have found that the air. in the preheater is heatedfto vsuch an eX-. tent that it expands in volume Yto about twiceits original size .and'it isthence de# liveredto the burner pipe through the pipe 27. B v preheating the air in this manner, the volume of the air delivered to the burner is materially reduced, which eliminates one of the greatest expenses in the operation of liquid fuel burners. Oilvapor entering the burner pipe through the pipe 29'travels at an acute angle to the flow of air through the jet 24 and strikes the wall of the burner pipe rearwardly of the forward end of this jet. The rear end of pipe 22 being closed byl the plug 25, compels the vapor to vtravel forwardly through the burner pipe to the opening 32 and it is thus deflected when it strikes the wall of the burner kpipe through this pipe in a forward direction. This tends to thoroughly break up the `particles of vapor and cause a substantially complete intermixing vvith the air. It further causes a whirling motion of the oil vapor and air and this mixture is delivered from the burner pipe in a whirling motion and burned.

Then steam is employed in place of compressed air` cold Water may be yadmitted to the preheater ll from the pipe 26 and the heat Within the preheater is sufficient to generate live steam which is delivered to the burner pipe in a manner similar to the compressed air. Heretofore, it has been necessary to employ live steam generated in-a separate source, such as an ordinary heating boiler Which rendered the use of such burners impossible Where a source of live steam was not available. Bj means of a burner constructed in accordance with the disclosure ofthe present application, l may either heat air to such an extent that a great deal of the heretofore necessary compression of the air is eliminated, or may heat cold Water and generate live steam to be employed in the burner.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape,`

size, and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, l claim:

l. A burner for liquid fuel comprising a burner casing, a burner pipe arranged in said casing, a retort surrounding said casing,

a preheater for fluid surrounding' said L,fi-eo esi tion, a connection between said retort and said burner pipe, and a connection between said preheater and said burner pipe.

3. In a burner for liquid fuels, a casing having open ends, a burner pipe arranged .in said casing, a retort surrounding said casing, a preheater surrounding said casing for preheating fiuid to be mixed with said fuel, and pipes connecting said retort and said preheater to said burner pipe.

et. In a burner for liquid fuels, means for heating the fuel, means for preheating a fiuid to be mixed with said fuel, a burner pipe closed at its rear end, a jet extending through the rear end of said burner pipe and'terminating therein, said jet being connected to said Huid heating means, and an inlet pipe for vaporized fuel arranged at a. rearwardly extending angle and communieating with said burner pipe adjacent the outlet end of said jet.

5 In a burner for liquid fuels, means for l'ieating the fuel` means for preheating a fluid to be mixed With said fuel. a burner pipe, a plug arranged in the rear of said burner pipe and having a central opening. a jet extendingthrough said opening and terminating intermediate the ends of the burner pipe, means for delivering said iuid to said jet, and an inlet pipe for fuel communicating with said burner pipe adjacent the outlet end of said jet and arranged at an angle thereto to initially deliver said fuel into said burner pipe rearwardly around said jet.

G. A burner for liquid fuels comprising a substantially tubular burner casinghaving open ends. a retort surrounding the rear of said casing, a preheater surroundingsaid casing forwardly of'said retort,` a burner pipe arranged adjacent t-he rear of said casing. a jet arranged in said burner pipe', a pipe connecting` said `iet to said preheater to deliver heated fluid to said liet, a branch pipe extending from said burner pipe intermediate the ends of said jet, and a pipe connecting said branch pipe to said retort.
